摘　　要：研究了ＣＰＶＣ／ＰＶＣ／ＣＰＥ 三元共混物的物理力学性能和流变性能。结果表明：共混物的维卡软化温度、拉伸屈服强度和熔体粘度随ＣＰＶＣ 用量的增加而明显增加；ＣＰＥ 的用量为４ ～８ＰＨＲ 时可明显改善共混物的冲击强度。s The physical,mechanical and rheological properties of CPVC/PVC/CPE blend were studied.The results showed the Vicat softening temperature,tensile yield strength and melt viscosity of the blend increased with the increase of CPVC content.When CPE content was 4～8 PHR,the impact strength of the blend was notably improved.
